d: Use d_comdat_linkage on generated internal decl.
This adds weak linkage to internal TypeInfo data on top of the existing
DECL_COMDAT, which helps in the unlikely event that two of the same
TypeInfo data ends up in multiple places.
gcc/d/ChangeLog:
* typeinfo.cc (TypeInfoVisitor::internal_reference): Call
d_comdat_linkage on generated decl.
